join

JOIN(1) 							   User Commands							   JOIN(1)

NAME

       join - join lines of two files on a common field

SYNOPSIS

       join [OPTION]... FILE1 FILE2

DESCRIPTION

       For  each  pair of input lines with identical join fields, write a line to standard output.  The default join field is the first, delimited
       by whitespace.  When FILE1 or FILE2 (not both) is -, read standard input.

       -a FILENUM
	      print unpairable lines coming from file FILENUM, where FILENUM is 1 or 2, corresponding to FILE1 or FILE2

       -e EMPTY
	      replace missing input fields with EMPTY

       -i, --ignore-case
	      ignore differences in case when comparing fields

       -j FIELD
	      equivalent to `-1 FIELD -2 FIELD'

       -o FORMAT
	      obey FORMAT while constructing output line

       -t CHAR
	      use CHAR as input and output field separator

       -v FILENUM
	      like -a FILENUM, but suppress joined output lines

       -1 FIELD
	      join on this FIELD of file 1

       -2 FIELD
	      join on this FIELD of file 2

       --check-order
	      check that the input is correctly sorted, even if all input lines are pairable

       --nocheck-order
	      do not check that the input is correctly sorted

       --help display this help and exit

       --version
	      output version information and exit

       Unless -t CHAR is given, leading blanks separate fields and are ignored, else fields are separated by CHAR.  Any FIELD is  a  field  number
       counted	from 1.  FORMAT is one or more comma or blank separated specifications, each being `FILENUM.FIELD' or `0'.  Default FORMAT outputs
       the join field, the remaining fields from FILE1, the remaining fields from FILE2, all separated by CHAR.

       Important: FILE1 and FILE2 must be sorted on the join fields.  E.g., use `sort -k 1b,1' if `join' has no options.   If  the  input  is  not
       sorted and some lines cannot be joined, a warning message will be given.
